Import qcow2 disk

Upload the image to a folder on Proxmox. I usually use /var/tmp create a VM in proxmox. Detach and remove the disk it created in the VM and run the following command.

qm importdisk [VM ID] [disk name and location] [Storage]

Example

qm importdisk 100 zabbix_appliance-5.0.2.qcow2 sas-01-Backup

Add the newly created disk in the proxmox interface.

Edit the boot order to add the new disk as the first boot device if not already.

Start the VM and pray to the tech gods.
